Eachstrap is conn'ected at its lower end to the adj ent stop 4 or 5 as the case may be and the upper end of each stra is connected with ablock 27 of the same thickness as the stop. Thus the straps 26 are arranged outside of the track bar and the ends of the bar swing behind the strap. j

The operating mechanism forthe door or track bar is arranged at opposite ends of the track bar, means being provided at one end for opening and closing the door, and means being provided at the other end for closing the door. The means for opening and closing the door is arranged on the opposite side of the stop 5 from the door opening, while the means for closing the door alone is arranged on the opposite side ofthe stop '4;

' from the door opening. The first named jacent to the track bar is provided with means comprises a lever 28, pivoted intermediate its ends as indicated at 29 to the side of the car and that end of the lever ada longitudinally extending slot 30. The track bar is provided at the said end with a pair of depending lugs 31 and a pin 32 is passed through registering openings in the lugs and through the slot 30 of the lever to pivotally connect the track bar to the lever.

Flexible members 33 and 34 are conscar below the adjacent k chains for-temporarily fholdin the chain in moved. After the door, has moved into either the position shown in Fig. 1, or that shown in Fig 2, the track bar will be held in such position by the weight of the door. This temporar holding mechanism is in the form of a bloc or bracke 41 secured: to the per and having a pair of pins 42 extend" toward the adacent chain, and adapt dii toenga site sides of a link of thefchain'tolfold the chain from. upward movement" It will be noticed that thefstopb'inclines away from the door openin per end. Because of the incfmedposition of;-

toward its "up the track bar when the doc: is-closed, one. side of the door is made ofgreater length than the other, so that when the'door is over the door opening the oppositesideothereof will be perpendicular regardles'sbff l the in clined position of the track ban The stop 5 is inclined to the adjacent side of the door w e litlie door nd with is open. A keeper 43 isprovided bot-;

the said keeperr being; at

This keeper prevents thdbottom nected with the respective ends of the lover, of the door from swinging outwafid; Each the said members being chains in the presstop 4 and 5 is braced by an angle bracket 44:

oor an member passes between the body and the hinged to thehasp, and the hasp coiiperates car. It will be evident that when the chain with a staple 47 on the strap 4 to hold the 34 is pulled Y the position of Fig. 1, the swung in a direction to depress that end of prevent disengagement of the staple and the the track bar adjacent to the stop 5 and the pin is supported. by a chain 49 connected door will roll of its own weight away from with the strap 4. It willbe noted that the over the door opening, that is, into the posipivot pin '29 which supports the lever 28 tion shown in Fig. 2. Vith the parts in extends laterally from an X-shaped late 50, this position when the chain 33 is pulled -which is secured to the inner face 0 the car downwardly with the parts in door closed. A pin 48 is provided for engaglever will be ing the staple after the hasp is in place to wall by means of bolts 51 which pass through the ends of the plate and through the car wall. The pin 29 is a species of huh or journal pin extending from the X-shaped plate through a suitable opening in the car Wall and the lever is held in place on the pin by means of a cotter pin. A guard is provided for the outer end of the lever "28 to limit the swinging movement of the lever to guide the lever in its movement. It will be noted that the lever 28 adjacent to the slide 30 is offset outwardly to permit its connection with the lug 31.

I claim:

In a means for swinging and locking an oscillating door track for a sliding door, the

- combination with a track pivoted intermediate its length of a lever pivoted adjacent to one end thereof intermediate the ends of the lever and having a slidable and pivotal connection with the track adjacent to one end of the lever, a chain connected with each end of tie lever and depending therefrom, a chain connected with the opposite end of the track and dependin therefrom, and means in connection with the last-named chain and with the outermost of the first-named chains for engagement by the chain to prevent the chains from upward movement.
